Filed: 1992-07-13
Abstract: PURPOSE:To easily obtain the member having excellent rigidity, strength and wear resistance and stable quality by hot working the powder formed with a nitride in the surface part obtd. by heating Al alloy powder contg. Mg in a nitrogen atmosphere. CONSTITUTION:A large amt. of AlN is formed on the powder surface in a solid phase or half solid phase region of 500 to 600 deg.C when the Al alloy powder contg. the Mg is prepd. and is heated in the nitrogen-contg. atmosphere. The Al alloy powder is plastically deformed and the AlN formed on the surface is finely ground and is dispersed into the Al alloy when the powder formed with the nitride in the surface part is hot worked to the desired phase material. The particle-dispersed Al alloy is produced in the production process for the blank material of the powder in such a manner. Further, the bond between the particles of the Al alloy powder and the bond between the Al alloy and the AlN are intensified and the desired nitride-dispersed Al alloy member is obtd.

Abstract: PURPOSE:To improve a sense of solidness of the appearance by applying paraffinic oil to the peripheral parts of the boundaries between a die-formed connection part between the ends of weather strips and the weather strips when both ends of the weather strips made of an EPDM-material are connected by die-forming. CONSTITUTION:When weather strips 21 made of an EPDM-sponge material formed by an extrusion molding is attached to a door sash, etc., the corner part of the door sash is formed by connecting both ends of the weather strips 21 through a die-formed connection part 22. When the die-formed connection part 22 is formed, both the ends of the weather strips 21 are first set to both ends of a die 3 having a corner-shaped cavity 33. At this time, both ends of a core 4 are forced into the openings of the weather strip ends, and the core remains in the cavity 33. Then, an EPDM-sponge material is injected into the cavity 33 to form the connection part 22, and the die is removed. After that, a paraffinic oil is applied to the peripheral parts including the boundaries 23 of the connections, so that the stepped difference 24 at both ends of the connection part is reduced.

IPC: G06K7/00
Filed: 1988-08-23
Abstract: PURPOSE:To reduce the number of constituting parts and to obtain the bar code reading device of high performance at a low price by changing the slice value of a video signal slice part in correspondence to the change of an output value from a scanning beam photo-detecting part which measures the output value of scanning beam. CONSTITUTION:A reflected light by the bar code symbol of the scanning beam to be outputted from a scanning part 1 is photo-detected by a reflected light photo-detecting part 3 and goes to be an electric signal. Then, the reflected light is amplified by a slice voltage generator 24, outputted to a comparator 6 and compared with a slice voltage which is the output of an integrator 5. Here, when the output of a laser tube is high, since the reflected light from the bar code symbol goes to be large, the output value of a video signal amplifying part 4 also goes to be large. Thus, a pulse train to exactly correspond to the width of a white bar wi and a black bar bi can be obtained from the comparator 6 and even when there is the output fluctuation of the laser tube, the high performance can be obtained. Then, the number of the constituting parts can be reduced.
